Unravelling the genetic basis of stuttering: GWAS meta-analysis highlights link with rare speech disorders

This study conducts a GWAS meta-analysis of stuttering, identifying genetic links with speech disorders and highlighting shared genetic architecture across different ascertainment methods.

Genetic contributions of noncognitive skills to academic development

This study shows noncognitive skills become more predictive of academic achievement over time and their genetic contribution increases with age.

Estimating effects of parents' cognitive and non-cognitive skills on offspring education using polygenic scores

The paper estimates how parents' cognitive and non-cognitive skills affect offspring education through environmental effects using polygenic scores and multiple study designs.

Multilevel Twin Models: Geographical Region as a Third Level Variable

This paper applies a 3-level multilevel model to twin data, showing that regional clustering explains 1.8% of children's height variance, which is ancestry-related and disappears after genetic principal components correction.

Investigating the Genetic Architecture of Non-Cognitive Skills Using GWAS-by-Subtraction

This study identifies 157 genome-wide significant loci associated with non-cognitive contributions to educational attainment, explaining 57% of genetic variance.

Intergenerational transmission of education and ADHD: Effects of parental genotypes

The paper examines how parental genotypes influence offspring education and ADHD, finding genetic nurturing effects for education but not ADHD.
